It looks like OSX's CoreText does funny things when vertical mode is 
requested for fonts that don't understand the concept of vertical mode.

I suggest to experiment with the pCFVertBool variable in 
main/vcl/aqua/source/gdi/ctfonts.cxx or by disabling the line setting 
the value for KCTVerticalFormsAttributeName altogether. If it shows that 
only fonts without OpenType's "vert" or "vrt2" feature are affected we 
could add a check for this and then work around this CoreText problem.

I've updated the AOO issue you reported accordingly.

Attachments are stripped from mails sent to this mailing list so the
